Subhas Kumar Ghosh, Sachchit Ghosh, Sai Shanmukha Narumanchi

摘要:

2019-2020年冠状病毒病(COVID-19)的持续大流行是由严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)引起的。这种致病性病毒在潜伏阶段能够通过易受感染的人群渐进传播。鉴于医疗保健的状况,敦促决策者控制感染的传播,尽量减少对卫生系统的压力,并确保公共安全。他们掌握的最有效的工具是关闭非必要的业务,并发出呆在家里的命令。在本文中,我们考虑了衡量世界各国政府采取的严格措施有效性的技术。通过分析封锁等控制措施的有效性,我们可以了解所做的决定是否是最佳的,是否减轻了医疗系统的负担。具体而言,我们考虑使用综合控制来构建替代方案,并了解如果采取不那么严格的措施,对健康的影响。我们对纽约州、美国、意大利和印度首都德里进行了分析,并展示了封锁措施如何发挥作用,以及与当前事态相比,反事实情景会是什么。我们发现,到2020年6月26日,纽约州的死亡人数可能会高出6倍,意大利的死亡人数可能会高出3倍。

英文摘要:

The ongoing pandemic of coronavirus disease 2019-2020 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This pathogenic virus is able to spread asymptotically during its incubation stage through a vulnerable population. Given the state of healthcare, policymakers were urged to contain the spread of infection, minimize stress on the health systems and ensure public safety. Most effective tool that was at their disposal was to close non-essential business and issue a stay home order. In this paper we consider techniques to measure the effectiveness of stringency measures adopted by governments across the world. Analyzing effectiveness of control measures like lock-down allows us to understand whether the decisions made were optimal and resulted in a reduction of burden on the healthcare system. In specific we consider using a synthetic control to construct alternative scenarios and understand what would have been the effect on health if less stringent measures were adopted. We present analysis for The State of New York, United States, Italy and The Indian capital city Delhi and show how lock-down measures has helped and what the counterfactual scenarios would have been in comparison to the current state of affairs. We show that in The State of New York the number of deaths could have been 6 times higher, and in Italy, the number of deaths could have been 3 times higher by 26th of June, 2020.
